CVI program using COM Method (agilentpnapulsed.dll)

[P.Barrenechea]

Hello,

I need to send/receive values to the "agilentpnapulsed.dll" remotely with a CVI program. Any example available? or explanation about how to do that? I need to write a Narrowband Pulsed application (to control remotely a PNA Network Analyzer).

The problems comes becasuse I don't know how to use the COM Methods?

Help please!

Thanks!

Hi Peli,

I'm not familiar with that specific COM server but I can tell you in general what steps you need to take to use that server in CVI. The best and easiest method to use a COM server in CVI is to use the ActiveX Controller Wizard to generate a CVI wrapper around this server.  Once you have registered the COM server, you can select Tools >> Create ActiveX Controller and then choose the agilent server.  Then you will walk through several dialogs and eventually, CVI will create C wrappers that expose properties and methods in a C fashion for you. Refer to the Using the ActiveX Controller Wizard to Generate Code in LabWindows/CVI KB for more information. Also check out the ActiveX Library Function Overview help topic. Additionally, depending upon your background, you might find the LabWindows/CVI ActiveX Controller For Visual Basic 6.0 Users tutorial.

Also check out the <CVI>\samples\activex directory for a variety of ActiveX examples.

Hope this helps!

Best Regards,
